This is a basic question from a recent convert to Capture NX 2. I'm sure it indicates a misunderstanding of how caching works. Unfortunately, neither of my CNX2 books elucidates the subject!

I have adopted the following NEF-centric workflow built around CNX2.

After completing some basic Develop and global adjustment steps, I create a version called "Master" and hit "Edit -> Save." The cache is updated in under a second; hopefully, the NEF on disc will also be updated later, e.g., when I exit from CNX2. While I'm working, the text across the top of the image window reads

DSC_0012.NEF* @ 16% | 4.8MB

This reassures me that my changes will eventually be reflected in the file DSC_0012.NEF (at least that's how I interpret it). Each time I hit "Edit -> Save," the cache is updated.

Continuing to work on the same image, I typically crop and resize, do some final sharpening, and "Save as" jpg for posting to a Web gallery. Once I do this, the text across the top of the image window reads

DSC_0012.jpg @ 50% | 55.2KB

Here is my question: Once I have "Saved as" jpg, how do I force a cache update WITHOUT creating another RGB image (tiff or jpg)?

For example, suppose I revert to the Master version, desaturate it, and create a new version called "B&W." I've spent a lot of time getting this right, and I'm worried that CNX2 might crash, so I hit "Edit -> Save." Oops: I just overwrote the color jpg! I could hit "Save as" and give it a new name, e.g., DSC_0012_bw.jpg. But I'm not ready to create the RGB image. I only want my changes flushed to the cache, the way they were before I created an RGB image. Is there any way to do this?
